Jupiter's Comet Collision Sites As Seen in Visible and Ultraviolet Light

July 18, 1994: This comparison of visible light (blue) and far-ultraviolet (FUV) images of Jupiter taken
with the Wide Field Planetary Camera-2 (WFPC-2) on NASA's Hubble Space Telescope
show how the appearance of the planet and of comet Shoemaker-Levy 9 impact sites
differ at these two wavelengths (1400-2100 and 3100-3600 Angstroms). The images
taken 20 minutes apart on July 17,1994 (around 19:00 UT), show the impact sites on the
southern hemisphere, from left to right, of comet fragments C, A, and E, about 12, 23, and 4
hours after each collision. Jupiter's satellite 10 is seen crossing above the center of the
disk, and the famous Great Red Spot is near the eastern limb.
